<h1>Mesa 18.1.6 Release Notes / August 13 2018</h1>

<p>
Mesa 18.1.6 is a bug fix release which fixes bugs found since the 18.1.5 release.
</p>
<p>
Mesa 18.1.6 implements the OpenGL 4.5 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 4.5.  OpenGL
4.5 is <strong>only</strong> available if requested at context creation.
Compatibility contexts may report a lower version depending on each driver.
